Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically a high-temperature resistant cable. Background Technology

[0002] A cable is a wire consisting of one or more mutually insulated conductors and an outer insulating protective layer. It is used to transmit electrical energy or electrical signals. Its core includes an internally energized and externally insulated structure. The conductors are usually stranded (such as concentric stranding, compacted stranding, etc.), and the outer layer is covered with highly insulating material to ensure safety.

[0003] In existing technologies, cables consist of a cable core conductor, an insulation layer, a shielding layer, and a protective layer. In underground mines (such as coal mines and metal mines), the ambient temperature often exceeds 40°C due to factors such as mechanical operation and geothermal heat. Moreover, the space is enclosed and the heat dissipation conditions are poor, so the heat generated by the cable easily accumulates. Over time, the insulation layer and the protective layer soften and decompose, exposing part of the cable core conductor to the outside, affecting the conductivity of the cable core conductor, and reducing the service life of existing cables. In view of this, a high-temperature resistant cable is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant cable that solves the problem of poor heat dissipation performance affecting the service life of cables, achieving efficient heat dissipation and extending service life.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature resistant cable, comprising cable cores, wherein three cable cores are fixedly arranged in a group inside a core-wrapping collar, the core-wrapping collar being triangular in shape, and a silver-plated copper mesh collar being fixedly arranged outside the core-wrapping collar, the silver-plated copper mesh collar being pentagonal in shape, a heat dissipation guide plate being arranged between the core-wrapping collar and the silver-plated copper mesh collar, a limiting collar being fixedly arranged outside the silver-plated copper mesh collar, and a plurality of fixing collars being fixedly arranged outside the limiting collars, with supporting pressure strips arranged in a circular array between adjacent fixing collars.

[0006] Preferably, the heat dissipation guide plate has honeycomb holes extending through its outer side, and a through hole is provided on the side that abuts against the core sleeve.

[0007] Preferably, the support strip is provided with a double conical surface, and a conical buffer space groove is left between adjacent support strips.

[0008] Preferably, the conical top surface of the support strip is higher than the fixing collar, forming an annular conical protrusion.

[0009] Preferably, the core collar is made of porous vacuum silicon.

[0010] Preferably, the honeycomb pores are arranged in three groups from large to small: upper, middle, and lower. The lower group has more small pores, and the honeycomb pores are arranged close to the core-enclosing collar.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model facilitates heat dissipation by combining the structure of the core ring, the silver-plated copper mesh ring, the heat dissipation guide plate, and the limiting ring. The nesting of the triangular core ring and the pentagonal silver-plated copper mesh ring keeps the relative position between the two rings fixed. At the same time, the gap between the sides of the triangle and the pentagon accommodates the heat dissipation guide plate, so that one side of the heat dissipation guide plate can tightly abut against the core ring to efficiently absorb heat, and the other side can stably fit against the silver-plated copper mesh ring to quickly transfer heat. This provides a stable structural foundation for heat absorption to the heat conduction path, ensuring heat dissipation efficiency. Therefore, it effectively solves the problem of poor heat dissipation performance of cables affecting service life and achieves the effect of efficient heat dissipation and improved service life.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 3 As shown, this utility model provides a high-temperature resistant cable, including a cable core 1. Three cable cores 1 are fixedly arranged in a group inside the core-wrapping collar 2. The core-wrapping collar 2 is triangular. A silver-plated copper mesh collar 3 is fixedly arranged on the outside of the core-wrapping collar 2. The silver-plated copper mesh collar 3 is pentagonal. A heat dissipation guide plate 4 is arranged between the core-wrapping collar 2 and the silver-plated copper mesh collar 3. A limiting collar 5 is fixedly arranged on the outside of the silver-plated copper mesh collar 3. A plurality of fixing collars 6 are fixedly arranged on the outside of the limiting collar 5. A support pressure strip 7 is arranged in a ring array between adjacent fixing collars 6. First, three cable cores 1 are fixed together inside the triangular core-wrapping collar 2. Second, when the triangular core-wrapping collar 2 is nested with the pentagonal silver-plated copper mesh collar 3, the three vertices of the triangle and the inner side of the pentagon can form evenly distributed contact support points. At the same time, a controllable and evenly distributed gap space will naturally form between the sides of the triangle and the sides of the pentagon. The heat dissipation guide plate 4 is accommodated through this gap space, ensuring that one side of the heat dissipation guide plate 4 can tightly abut against the core-wrapping collar 2 to efficiently absorb heat, and the other side can stably fit against the silver-plated copper mesh collar 3 to quickly transfer heat. This provides a stable structural foundation for the heat absorption to the heat conduction path and ensures heat dissipation efficiency. At the same time, when the pentagon wraps the triangular structure on the outside, its polygonal structure can support the triangular core-wrapping collar 2 from more directions. After the two are combined, the stable inner support of the triangle and the multi-directional outer fixation of the pentagon complement each other, so that the relative position between the two collars always remains fixed. Then, the support strip 7 between adjacent fixed collars 6 can resist external bending force.

[0016] like Figure 2 and Figure 3 As shown, the heat dissipation guide plate 4 has honeycomb holes through its outer side, and a through hole is provided on the side that abuts against the core ring 2. The core ring 2 is made of porous vacuum silicon material. The honeycomb holes are arranged in three groups from large to small, with the lower group having more small holes. The honeycomb holes are arranged close to the core ring 2. The heat from the core ring 2 can be directly absorbed through the through holes on the contact surface between the heat dissipation plate 4 and the core ring 2. At the same time, the porous vacuum silicon material of the core ring 2 can improve the barrier to external heat. Subsequently, the honeycomb holes on the outside increase the contact area with the silver-plated copper mesh ring 3, accelerating the conduction of heat from the heat dissipation plate 4 to the silver-plated copper mesh ring 3, thus achieving rapid heat dissipation.

[0017] like Figure 3 As shown, the support strip 7 is set with a double conical surface, and a conical buffer space groove is left between adjacent support strips 7. The conical top surface of the support strip 7 is higher than the fixing collar 6, forming an annular conical protrusion. The double-conical design of the support strip 7 between adjacent fixed collars 6 can distribute the external radial pressure to multiple support points. The conical buffer space groove between adjacent support strips 7 provides deformation buffer space when under pressure. At the same time, the conical top surface of the support strip 7 is higher than the annular conical protrusion formed by the fixed collar 6, so that when the cable comes into contact with the outside, it will preferentially bear the force through the protrusion, reduce the overall contact area, reduce the damage of external friction to the cable, and the protrusion structure enhances the cable's resistance to bending.

[0018] Working principle and usage process of this utility model: By nesting the triangular core ring 2 and the pentagonal silver-plated copper mesh ring 3, the stable inner support of the triangle and the multi-directional outer fixation of the pentagon complement each other, keeping the relative position between the two rings fixed at all times. At the same time, the gap space formed between the sides of the triangle and the sides of the pentagon accommodates the heat dissipation guide plate 4, so that one side of the heat dissipation guide plate 4 can tightly abut against the core ring 2 to efficiently absorb heat, and the other side can stably fit against the silver-plated copper mesh ring 3 to quickly transfer heat, providing a stable structural foundation for heat absorption to the heat conduction path and ensuring heat dissipation efficiency. Then, the support strip 7 between adjacent fixed rings 6 can resist external bending force.
